sound - sound player facility

### Calling Sequence

  `sound(y [,fs,bits,command)`

### Parameters

- `y`: real vector
- `fs`: real number, sampling frequency in sample per second (default value is 22050)
- `bits`: real number, number of bits (unused)
- `command`: Only used on Unix systems it gives the name of the command to use for playing sound (wav) files. The defaut value is `aplay`. If set `/dev/audio` then a 8 bits mu-law raw sound file is created and send to `/dev/audio`

### Description

`sound(y,fs)`plays the sound signal given by matrix `y` (with sample frequency fs). In fact this function is just a wrapper for `playsnd`. Values in y are assumed to be in the range -1.0 <= y <= 1.0. Values outside that range are truncated. The number of rows of `y` gives the number of channels. `sound(y)` plays the sound at the default sample rate of 22050 sample per second. `sound(y,fs,nbits)` plays the sound using `nbits` bits/sample if possible (it is in fact unused). Most platforms support bits=8 or 16.

### Examples

      // a two channel signal
      y=loadwave('SCI/demos/signal/sound/chimes.wav');
      sound(y)
